Abstract
A GPS signal receiving section measures a Doppler frequency of a carrier wave to output a three-dimensional velocity vector to a CPU,The CPU,calculates a cumulative distance from a signal receiving interval and velocity data to compare between the cumulative distance stored in a RAM,and the distance point data previously stored in the RAM,Where the cumulative distance exceeds the distance point data, a lap time is calculated and displayed on a display section,based on the time count data sent from the time count circuit,Further, the CPU,calculates and displays on the display section,a time to arrive at the predetermined moving distance from the velocity data, the cumulative distance and the predetermined moving distance stored in the RAM
